The power supply is suitable for Placid Industries brakes up to 220 lb.-in. & clutches up to 130 lb.-in. torque. The power supply is a 

constant current type, with a 3/4 turn potentiometer for setting output current from 0% to 100%.  The cutput current can also be 

controlled with a 0-10 Volt Input Signal or Follower Arm Potentiometer.   The SPAN adjustments set maximum and minimum current 

levels.
